This may or may not help explain things......https://thehackernews.com/2018/01/meltdown-spectre-vulnerability.html

Thanks for this. Though I'm not sure how well I understand some parts.
In essence, and from technical news posts, my understanding is that (anyone has better knowledge may correct me):-
* Intel processors since the 1990s are vulnerable to this because of using the "speculative" approach. But cancelling this approach can greatly slow processing in processor-intensive tasks.
* AMD prcoessors are technically unknown according to some reports, and unaffected by others; and possibly affected in their own right by others (I don't have the sources to hand). My take is that it is unknown/thought unlikely to affect AMD processors.
* My take is also that it requires local access to exploit (as known at the moment), but whether that will continue the case isn't reported on in the items I've read.
* This has been known about for some time.
* The problem requires fixing at the OS level.
I'm presuming that using Intel processors with the current kernel 4.4.x series in Linux Lite leaves it theoretically vulnerable; though I understand that at present there is no malware exploiting the problem?

The video lost me about 10 seconds after it started. I have no idea what he is talking about.

@Jerry, watched video but it was beyond my understanding. :-[ Glad my main computer is AMD based on the recommendations of the ghost formerly know as Spatry. ;)
